I am new to this site, but see you have tremendous experience in various exchange scenarios and truly appreciate that answer.

Because going from $125k to $225k (+80%) in house value is a tremendous forced appreciation (unless you bought it way underpriced).

But if you think positively and creatively, learn all you can about your new industry, you can keep a clear, focused and calm state of mind which will pay off tremendously in being able to say exactly the right thing at exactly the right time, in exactly the right way.I wish you luck in this wonderful, exciting and rewarding career.

I had a tremendous amount of flexibility.

There is a tremendous affordable  housing crisis in west coast states, primarily California. 

It is a no-brainer business (you never see them go broke) and some states allow tremendous profit potential (FL allows 304% APR).

Since that time it's tremendously appreciated in its value and now I am thinking if I should sell it or continue renting it out perhaps for another year or so.

Plus, this does not sound tremendously dated or obsolete building situation (built mid-century and updated since)....I do, though, like when landlords are responsible and don't squeeze all the juice out of the lemon and exit stage left (and pass on all the deferred capital costs to a less informed buyer, like a hot potato).

You've done some tremendous things over the past few years and are an inspiration!

The rules vary tremendously by state.
